[Valgrind-users] Initialize a char[] to use sprintf function

[aruperez <arm...@gm...>]

I'm using valgrind a in'm having a little problem, 

I'm using the function sprintf to convert an int to a char *
if you check the example how to use this function in www.cppreference.com 

there is something like this 
char result[100];
int num = 24;
sprintf( result, "%d", num );              

however when i do that in my code, valgrind reports the following error
==16490== Use of uninitialised value of size 4
==16490==    at 0x43876E4: __printf_fp (in /lib/libc-2.6.1.so)
==16490==    by 0x4382FE0: vfprintf (in /lib/libc-2.6.1.so)
==16490==    by 0x439E91B: vsprintf (in /lib/libc-2.6.1.so)
==16490==    by 0x438A42D: sprintf (in /lib/libc-2.6.1.so)

what should i do?? initialize the char[] before calling the function?, which
is the best way to do it becuase i tried assigning = "" but valgrind still
complained.

thanks for your help.
